Deploy and Host eweser-db on Railway

eweser-db is a local-first, user-owned database stack built on Yjs CRDTs. It lets developers build real-time, offline-capable apps where users own their data instead of being locked into a single platform. This Railway template deploys the full stack: auth API, auth pages, sync server, aggregator, note app, and PostgreSQL.

About Hosting eweser-db

Hosting eweser-db means deploying the core services that make local-first sync and self-hosted user data possible. On Railway, that includes the auth API, auth pages, Hocuspocus-based sync server, aggregator, note app, and PostgreSQL. The frontend apps connect to the auth and sync services, while the aggregator indexes server-side data for search and discovery. Because this is a monorepo, each Railway service points at the same repository but uses its own Dockerfile and environment variables. Railway handles deployment, networking, restarts, and scaling, while you keep control over the infrastructure and user data.

Common Use Cases

Self-hosting a user-owned backend for notes, documents, and collaborative apps
Building offline-first apps with real-time sync across devices
Launching interoperable apps that share data over strongly typed Yjs documents

Dependencies for eweser-db Hosting

PostgreSQL for auth and server-side application data
Railway service variables and secrets for auth, sync, and cross-service URLs

Implementation Details

Each Railway service in this template uses the same monorepo root and selects its own Dockerfile via RAILWAY_DOCKERFILE_PATH.

RAILWAY_DOCKERFILE_PATH=packages/auth-server-hono/Dockerfile
RAILWAY_DOCKERFILE_PATH=packages/sync-server/Dockerfile
RAILWAY_DOCKERFILE_PATH=packages/aggregator/Dockerfile
RAILWAY_DOCKERFILE_PATH=packages/ewe-note/Dockerfile
RAILWAY_DOCKERFILE_PATH=packages/auth-pages/Dockerfile
Core cross-service environment variables include:
DATABASE_URL=${{Postgres.DATABASE_URL}}
SYNC_AUTH_SECRET=${{auth-api.SYNC_AUTH_SECRET}}
SYNC_SERVER_URL=wss://sync-server-${{RAILWAY_PUBLIC_DOMAIN}}
AUTH_SERVER_URL=https://${{RAILWAY_PUBLIC_DOMAIN}}
